</view>



3、JS部分:


import $wuxCountDown from 'countdown/countdown'
export {
 $wuxCountDown, 
}
import { $wuxCountDown } from '../../components/wux'
 vcode: function () {
 if (this.c2 && this.c2.interval) return !1
 this.c2 = new $wuxCountDown({
 date: +(new Date) + 60000,
 onEnd() {
 this.setData({
 c2: '重新获取验证码',
 })
 },
 render(date) {
 const sec = this.leadingZeros(date.sec, 2) + ' 秒后重发 '
 date.sec !== 0 && this.setData({
 c2: sec,
 })
 },
 })
 }
